VALVE.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application filed December 1, 1913. Serial No. 803,867.

To all whom it may concern Be it known that I, WILLIAM KANE, citizen of the United States, and resident of Philadelphia, county of Philadelphia and State of Pennsylvania, have invented an Im- .provement in Valves, of which the following is a specification. v

The object of my invention is to provide a simple and inexpensive form of valve more especially intended for use in gas burner systems, though while more particularly useful in this connection, it may be used for many purposes where Valve is desired.

In gas valves as heretofore constructed, it has been found in practice that the plug or ground key type more generally used, is

subject to constant wear as it is turned back and forth, and th effect is such as to cause leakage after the valve has been in use for some time. connection with this type of valveto employ springs to take up the wear of the ground plugand'to generally adjust conditions so as to prevent leakage, but such devices increase the friction and wear and sooner or later th'ereis a leakage of gas around the plug.

In my present invention I hav devised a construction whereinthe friction and consequent wear and tear of the parts are reduced to a:minimum, and wherein the valve body is made leak-proof withoutthe aid of cumbersome 'stufling box structures or like packing devices, and further, the closing movement of the valve is in a direction with the v to seat within a counter-sunk portion 11 of gaspressure so that the latter serves as an efi'ectlve auxillary means for ma1nta1n1ng the valve 1n closed pos1t1on.

My invention has for a further object to.

rovide a valve operating mechanism in which'the valve stem or its adjuncts are always freely movable and consequently the annoyance caused by sticking valve stems is entirely eliminated.

A further object of, my invention is to provide a valve structure wherein the dis-- viding a novel type of adjustable needle valve which may be readily set and adapted for any particular gas pressure so that no matter what the pressure conditions may be, there is never an excessive supply to the burner or burners.

Figure 1 represents a sectional elevation a tight leak-proof It has also been proposed in of a valve embodying my invention; Fig. 2

represents aside elevation of the valve and its stem; Fig. represents a plan of the valveyand F g. 4 represents a side elevation of a portion of the valve operating mechamsm. Y

Referring to the drawings, similar numerals of reference indicate corresponding parts.

1 designates the valve body or casing which is, as usual, of hollowconstruction and provided with the inlet opening 2 and outlet opening 3, the said openings as here arranged being substantially at right angles to each other. In addition to these openings the valve body 1 is provided with a I bore 4- preferably in alinement with the. inlet opening 2 and also provided with a threaded opening 5 alined with theoutlet opening 3. f

6 designates the valve seat formed in the body 1 adjacent the inlet2, andis adapted to be opened and closed by the valve member 7, which in the preferred form is of beveledconstruction to conform to the general contour of the seat 6. The valve piece or member 7, as here shown, is integral with or suitably-secured to a stem 8 which, passes 3 transversely through a valve body 1 by way of the bore 4, from which latter it projects a suitable distance to receive a grooved spool 9 fixed to the end of the stem 8 and serving to transmit movement from a suitable operating mechanism to the said stem 8. In the 1 present instance this spool 9 is provided with a cone-like portion 10 which is adapted endof thepin has fixed thereto in any well knownmanner the crank'arm 15 which. is

oint.

It will be noted that the valve adjuncts pressure of the gas acts as an auxiliary means to hold the valve piece 7 in closed 110: sition so that after a closing the valve stem 8 by throwing the weighted arm in the proper direction, the aforesaid pressure will tend'to maintain it in closed position, thus eliminating the danger of ghollow valve body having an inlet and an lealrageirrespective of the valve position.

In the present embodiment of my inven tion I have provided a slot 17 at a suitable point in the stem'8for the purpose .of allowing free; movement therethrou-gh of a needle valve stem 18, this latter having the'customary cone-shaped end 19 atone end while its opposite end 15' have shown provided with a screw thread 20. The

threaded end 20 is in engagement with a closure or" cap 21 threaded into the opening 5 to effectually close the same so thatthere is no opportunity for the gas to leak at this open a predetermined distance which be varied according to the-pressure of the main gas supply, and after it is once adjusted icy-turning it with respect to the v closure it remains permanently lined in this position and the supply of gas: through the opening will consequently be in proper proportion to the aspressure.

Ars here shown F have formed the; needle opening or gasoutlet 22 the endof' a ca-pnipple 23; which isthreaded into the outlet opening 3- of the valve body, and the gas therefor entering through the inlet 2 and passing by way of the valve seat 6 is discharged through the needle opening 22;

Inthe operation of this valve it will be noted that when the valve 7 is: open and gas is flowing through the body, there is no chance of leakage through any of the joints since the-opening 5 is. tightly sealedby the closure 21, and the jointbetwecn the stem 8, and the body 1 is perfectly sealed by the spool 9 under the constant pressure of the I arm 15: under theaction of gravity; When the valve 7 is closed and correspondingly thebushing 9yhas moved away from the body 1, the aforesaid joint of the stem 8 is not subject to. the gas pressurewowing-to the fact that the valve '1 is seatedand'so held tention is further directed to. the fact that the parts are so arranged that there is; little wear, the; friction is reduced to a minimum T and injview of the gravity controlled opera ring mechanismfor the stem; 8 there can be no sticking of theyvalve stem or its. ad-

juncts.

It. will further be apparent that a very slight movement; of the arm 15 out of the vertical will cause it to drop-by gravity action, thus promptly shifting" the valve to movement of The needle valve 18; is normally lVhile. I havedescribed my invention in yminor details may be modified witho'ut'de .parting from the spirit of the invention. Having thus described my invention, what I claim and desire to secure by Letters 'Patent is 1 1 In a device "of the character stated, a
